Judgment day is read as a reckoning with your own conscience. The dream reflects fear of being evaluated, or a wish for things to finally be set right.
When this appeared in your dream, what were you feeling?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
